T all 11-71 0222 it may concern:

'Be it known that I, ARA U. LEONH SUSER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use: ful Improvements in Shearing-Machines, of which the following is a full, clear, and exact specification.

This invention relates to shearing machines, and more particularly to stopping and locking mechanism therefor.

One of the objects of this invention is to insure the proper stopping of material to be cut into definite lengths.

Another object of this invention is to insure the proper control of the stopping mechanism.

A still further object is to provide a simple and effective adjustable locking mechanism for the shear stop of the shearing machine.

These and other objects are accomplished by providing in a shearing machine the combination of a movable shearing member, a movable stop member, an operative connection between said members, and means for adjustably locking said stop member.

The invention is illustrated on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary front elevation of a shearing machine embodying my invention; Fig. 2 is a fragmentary plan View of the same machine; Fig. 3 is a side elevation, parts being in section, of the same machine, the section being taken in the planes of the irregular line 3-3 of Fig. 1; Fig. 4 is an enlarged view of the stopping and locking mechanism taken in the plane of line 4-4 of Fig. 1; Fig. 5 is a plan view of the stopping and locking mechanism; Fig. 6 is a rear elevation of the locking mechanism; and, Fig. 7 is a front elevation of the stopping mechanism.

The various novel features of my invention will be apparent from the following description and drawings, and will be particularly set forth in the appended claims.

'This shearing machine includes a main standard 10 supporting the stationary shearing member 11, and having a guiding and supporting portion 12 in which the head 13 of the movableshearing member is actuated, the movable shearing member 14 being secured to said head. The movable shearing machine member 14 may be actuated in any suitable manner. This machine also includes a table 15 comprising a series of pedestals 16 having a horizontal surface 17 upon which material to be sheared is supported. Roller members 18 also are mounted in this table for feeding the material to be sheared along said table. This table, which is of considerable length, is made up of sections which are held together by a large bolt 19 passing through openings 20 in a guiding member 21, which is secured to the back portion 22 of the table, the bolt 19 bein supported to prevent sagging thereof 12x17 anges 23 formed Within said member which is engaged by a pinion 25 mounted upon one end of a shaft 26 having an operating hand wheel 27. This shaft is mounted in a bearing portion 28 of a carriage 29. This carriage 1s provided with guiding and sliding portions 30 which cooperate with guidin and sliding portions 31 formed on the guiding member 21. By means of the rack and pinion arrangement the carriage 29 may be slid along the table by operatingthe hand wheel 27. In this carriage 29 is mounted a stop member 32, which is mounted upon a shaft 33 having bearings in the carriage flanges 34. The sliding head 13 of the -85 movable shear member 14 is operatively connected to the stop member 32 in the following manner: Mounted upon the upper portion 12 of frame 10 of the shears is a bracket 35 in which is pivotally mounted a lever 36,

to the sliding head 13, the other end of which lever, having a slotted portion 38 for the reception of an adjustable link 39 piv-- otally connected to an arm 40, which is secured adjacent the shearing members to a squared shaft 41. This squared shaft 41 is provided with rounded or journal portions 42 by means of which it may rotate in the table 15. shaft is an arm 43 secured in the carriage 29,- a said arm having pivotally connected-to one, end thereof links 44, which, are in turn, pivotally connected to the movable stop member 32. The adjustable link member 39 is pro- 105 'vided with a projection 45 which normally engages the under portion of lever 36 adjacent the slot 38, a spring 46 tendingto hold the projection 45 insuch position. 1v-

otally secured to the link 39 is a link 47, to 110 Formed on the top of this guiding" one end 37 of which is pivotally connected Slidably secured to the squared 0 -one end f which is pivotally connected at hand operated lever 48 pivotally mounted in brackets 49.

.As shown in full lines in Fig. 3 the stop member 32 is in its raised position, the head 13 of the movable shearing member 14 also being in raised position. The stop member 32 is held in this raised position by means of the releasable connection between the lever 36 and the adjustable link 39, the pro- .Fig. 3, and the link 39 passes upwardly through the slot 38 in lever 36. With the stop in this lowered position material such as a metal bar may be passed between the shearing members 11 and 14, and slid along the table 15and over the rollers 18 until such bar strikes the stop member 32, whereupon further movement of the bar to be cut is arrested. At this point-the movable shear member 14 through the action of its operating head 13 may be lowered for cutting the bar. At the sametime due to its connection with the operating head 13 the free. end of lever 36 Will rise to a point permitting the projection 45 of link 39 to pass under a portion of the lever due to the action of spring 46. With the parts in this position it is apparent that when the movable shear member 14 and its head 13 are raised the stop member 32 also will be raised due to the operative connection between said parts.

The stop member 32 is mounted on the carriage 29 to enable the cutting of material into different lengths. As stated above the carriage may be actuated by operating the hand wheel 27, which in turn rotates the pinion 25, the latter meshing with the stationary rack 24 over which said pinion passes. The carriage may be locked in any adjusted position by a locking member 50, includingahandle 51 and a plurality of locking projections 52 which are adapted to engage with teeth 53 of the rack 24. This locking member also is provided with a projection 54, which may engage the member 21 for limiting the movement of the locking member in one direction. This locking member is provided with an internally threaded portion, the threads of which engage the threads 55 of a threaded member 56, which is movably supported in the carriage flanges 34-. This threaded member 56 passes through and is journaled in these flanges 34, and has at one end a head 57 and at the other end an opening 58 for the recepmaaeva tion of a wrench for actuating the thread member 56 for final adjustment. This threaded 1memben56 also is provided with a mined for cutting bars or other material into desired lengths within very small fractions of an inch. For the rough adjustment, the hand wheel 27 may be actuated to move the stop to approximately the proper place, during this time the locking member 50 being in position shown by dotted lines in Fig. 4, that is, with the locking projections 52 out of engagement with the teeth of the rack 24. When the stop 32 has been moved to approximately the proper osition, the locking member 50 is thrown into the full line' position shown in Fig. 4, placing the locking projections 52 in mesh with the teeth of the rack-24, thereby locking the carriage in such position. If, however, it is desired to move the carriage and stop member a small distance one wayor the other this may be accomplished by loosening lock nut 59 and turning threaded member 56 until the stop lsaccurately placed in the proper position, whereupon the lock nut 59 may be tightened. By means of this arrangement the stop member may be accurately adjusted and locked in such adjusted position. For measuring purposes the table is provided with a scale 60 marking the number of feet, and the carriage is provided with a scale 61 indicating fractional parts of a foot. This furnishes a micrometer arrangement for accurate measurements. With the stop member 32 in the positionshown in Fig. 1 the scale indicates that the distance between the shear members 11 and 14 and the stop member 32 is thirteen feet, ten and one-half inches.

In summing up the operation of this machine let it be assumed that it is desired to cut from a pieceof material a bar thirteen feet, ten and one-half inches long. The stop member 32 will be placed in the proper position, as hereinabove described, and the hand operated lever 48 moved to the left, as viewed in Fig. 3. This movementof lever 48 will shift the link 39 into a position such that the projection 45 will escape its cooperating locking portion on lever 36, permitting the stop member 32 to fall due to its own weight, to its lower operative position, as indicated in dotted lines in Fig. 3. The bar or material to be cut will then be passed between the shear members 11 and 14 and fed over the rollers 18 and surface 17 of the table 15 until the end. of the bar strikes the stop member 32, causing further movement of said bar to be arrested. At this point the movable shearing member 14 may be lowered for shearing off the bar. As the movable shearing member is lowered the right hand end of lever 36, as viewed in Fig. 3, is lifted sufliciently high to permit spring 46 to move the projection 45 of link 39 under the lever 36, whereupon during the raising movement of the movable shearing member 14 and its head 13 the stop member 32 will be raised to its full line position, as shown in Fig. 3. If it is desired to out other bars into the same length the operation may be repeated. If it is desired to cut bars into different lengths, the position of the stop member may be changed, and stop member locked in its adjusted position, as hereinabove described.

It is evident that there may be various modifications of my invention as herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope-of my invention asset forth in the following claims.
